Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

In Interstellar, Miller’s planet orbits close to the black hole Gargantua, where gravity is so strong that time runs much slower. This is gravitational time dilation, a prediction of Einstein’s ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...
